In the bridge pavement, the moisture that has entered from the pavement edge and cracks causes delamination and potholes. For this reason, appropriate measures to stop water from entering the pavement are required. The purpose of this study was to evaluate water stoppage measures. We examined a method to detect the moisture that entered between the pavement layers by measuring the electrical resistance. As a result, the possibility of detecting moisture between layers by this method became clear.
